util/cbfstool: Add AMD BIOS compression tool for PSP
Add a utility to generate a compressed BIOS image for AMD Family 17h. If the input is an elf file, the utility extracts the program portion for compression. Otherwise the file is compressed as-is. In modern AMD systems, the PSP brings up DRAM then uncompresses the BIOS image into memory prior to x86 beginning execution. The PSP supports a zlib engine, and interprets the first 256 bytes as a header, where offset 0x14 containing the uncompressed size. For further details, see AMD Platform Security Processor BIOS Architecture Design Guide for AMD Family 17h Processors (NDA only, #55758).
